3 Claims.

This` invention relates to improvements in record controlled tabulatorsand has particular reference to card analyzing means therefor, thepresent disclosure being a division o f my co-pending application SerialNo. 13,017, led March 4, 1948.

An object of the invention is to facilitate access to the interior ofthe card analyzing mechanism of a tabulator in the event of a card jamso that any mutilated cards therein may be readily and quickly removed,and to also enable repairs and replacements to be made with comparativeease. Another Vobject is to provide the analyzingvl section of astatistical card machine with relatively movable frames each of whichcontains certain operating and control mechanisms that cooperate intheranalysis of cards and in the transmission of such analysis to otherparts of the machine, and wherein a drive for ksaid mechanisms ismountedy in one of saidfframes for detachable connection to portions ofthe mechanisms in the otherframe to permit of said frames beingrelatively moved apart to open position.

In-carrying out the above objects, the invention provides a constructionin which the analyzer section of the tabulator comprises, generally, amain frame :carrying portions of the card analyzifn'gY mechanismincluding one of the plates forma partof a chamberinto which cards arefed for analysis, and an auxiliary frame movable to open positionrelative to the main frame and supporting therein, among other elements,portions of the analyzing mechanism anda second plate which cooperateswith the rst plate to form said card chamber and which is movable withsaid auxiliary framewhen the latter is adjusted to openposition, tosupport the two plates of the chamber and thus fully expose for readyaccess and removal any cards in the analyzing section.

The inventive idea involved is capable of receiving a variety ofexpressions one of which, for purposes of illustration, is shown in theaccompanying drawings; but it is to be expressly understood that saiddrawings are Aemployed merely to .facilitate the description of theinvention as a Whole and not to define the limits thereof, referencebeing had to the appended claims for this purpose.

Inthe drawings:

Fig. l is a fragmentary side elevation of the analyzing section of atabulator constructed in accordance with the invention;

Fig. 2 is a view similar to Fig. l, partly in section, showing the upperauxiliary frame of the analyzing unit in partially open position; andVFig. 3 is a fragmentary vertical transverse section through theanalyzing unit.

The analyzing section comprising the features of this invention includesthe front and back plates 3i and 32 and a transverse wall 35 suitablycarried upon the base of the tabulator, the wall separating saidanalyzing section from the remainder of the machine which forms no partof the present invention and by which the analysis of the record cardsis transferred to the printing and accumulating mechanisms of thetabulatorl for the control thereof. Said plates 3|, 32 constitute themain frame of the analyzing unit and have pivoted to the upper portionsthereof, at 38, the two rails 39 of an auxiliary frame which furthercomprises the side plates 40 and 4I and a cover plate 42, said pivotalconnection permitting said auxiliary frame and the entire mechanismsupported thereby to be swung upwardly to a substantially verticalposition, after effecting certain disconnections to -be later described,in order that ready access may be had to the interior of the analyzingsection. The auxiliary frame is held in its horizontal operativeposition by removable dowel screws 43 extending through the rails 39 andinto the side plates 3i, 32, and to adequately support said auxiliaryframe in its closed posiv tion the opposed side rails 39, which arelaterally oifset relative to the plates 3|, 32, carry blocks 44 whichrest upon the latter plates, as shown in Fig. 3.

to one end of the transverse shaft 58 (Fig. 2) having bearings in theplates 3l, 32 and Operable to control the various functions of theanalyzing section of the machine, as fully set forth in the aboveidentified application.

Pairs of upper and lower card feed rollers 'l'l have their shaftssupported in the plates 3|, 32, those rollers shown in Fig. 3 being theintermediate pair located vertically between the sensing and analyzingstations generally indicated at 19 and 8l at which cards are comparedfor group control purposes. The shaft of the lower roller of said pairextendsthrough the front plate 3| and is geared to the horizontalcounter shaft 98 by a worm 99, and similar pairs of rollers are alsogeared to the latter shaft and to the shaft on the rear side of themachine so that the various pairs of rollers will operate in unison tofeed cards ejected from the magazine 63 carried by the side rails 39 andtransmit them to and 3 through the card chambers 18 and 80 at thestations 19 and 8|, after which said cards are deposited by the last setof rollers 11 to the left of Fig. 2 into a stacker chamber (not shown).A picker mechanism offthe usualt type is utilized to feed cards from themagazine 66 and is operatedA from the rock shaft 1| connected throughthe crank 12 to a link 13 actuated by bell crank 14 controlled by a cam(not shown) onthe shaft 58.

The two mentioned stations 19, 8| include, re-v spectively, thevertically reciprocating lower pin boxes |03 and |03a that contain the'sensingl pins |64 by means of Which'perforations in the cards at saidstations are simultaneously sensed while cards are momentarily heldinthe card' chambers by the card stops= 82'- pin boxes are of identicalconstruction except that the box |33a contains an additional pin. |04 ineach row individual to a card column and used for control purposes.Stations 19, 8| further comprise the upper pin boxes |09', |`09asupported in position above' the pin boxes |03, |03a by attachment tothe blocks 44 on the' rails' 39 so as to be movable with' the latter andcarry with them the card stops 82 when the auxiliary frame of which saidrails form a part is swung' to open position. Secured to the pin boxes|09, |09a are the upper plates 18a and 88a. which cooperate with thelower plates 18h, 80h to'form the card chambers 18, 88, the' latterplates being ailixedto rails 83k secured to the side plates The upperpin boxes |09, |0911' contain, respectively, the rows of pins ||0, whichare controlled by the sensing pins |04' in the lower pin boxes and when.said pins H', are elevated by said pins |4 passing through perforationsin cards being sensed at the two stations, lock plates ||4 in the upperpin'boxes momentarily hold' those pins H8, elevated which have beenraised bythe pins |04 during' the sensing and analyzing operations'. Thelock plates ||4 are under the combined control of reciprocating. crossbails ||5, only one of which is, shown herein. As fully describedinsaid' copending application, said plates areshifted into lockingposition relative to elevated pins H0, I|| and remain in suchv positionuntil' the bails are returned to restore' said plates andthereby releasethe elevated pins following th'eperformance of their functions. Arock'shaft |8'con'trols the reciprocation of the bails to shift the lockplates into locking position and saidshaft'c'arries a crank |20 to whichis' detachably connected a link |2| joinedv to a lever' |22' operated"by a cam (not shown) onthe shaft 58.

The card stops 82 are controlled from a cam on said shaft' 58 engaging alever |25 which is directly in front of the lever |22 and to which isconnected a link |26 that is detachably joined to a rock shaft |21 whichcontrols the operation of said stops.

y From the construction thus far described, it will now be apparent thatwhen the upper auxiliary frame is swung to open position about itspivots 38, the upper pin boxes |09; |09a and' the. upper plates 18a. and80a, and other mechanism to be described which is contained in saidframe, will be separatedfrom the lower pinboxes |03, |03a and thechamber plates 18h, 8017 to thus fully' expose the feed rollers 11 and'open the card chambers 18, 80 so that mutilated?- cards may be easilyremoved in the event of a card' jam in the analyzer, or. shoulditbedesired to' effect` repairsit'o or replacement of parts thus exposed.

The two lower Cooperating with the pins ||0, in the up'-l per pin boxesis a reciprocating scanning device generally indicated at 2|| and whosereciprocation is controlled from the shaft 58 by complementalv cams2|-2" thereon acting upon levers 2|`5, 2'||5 onone sidev of the machinecone nected by a cross bar 2|1, there being a similar arrangement oflevers on the opposite side of the machine also controlled bycomplemental cams 2|`2. The lever 2|8 on one side of the machine and itsequivalent 2|6a on the other side thereofextend upwardly and aredetachably joinedy to4 links 220 and 220er connected at 22| to thescanning frame so as to reciprocate the same. The scanning frame, asfully described insaid co-pending application, carries sensing pawls-223Y which. travel over the pins ||0, in the two upper pin boxes and aretripped by elevated pins therein to, control the movements of Aslides225 which, in turn, control the operation ofv bars |36 forming part ofthe data transfer mechanism (not shown) located to the left of the wall35, and also actuate bell cranks' 243 forming part of a change ofdesignation control mechanism contained within the upper part of theauxiliary frame between the plates 40, 4|', said mechanism furtherincluding the setting keys 263 for controlling the type of totals' to betaken upon a change of' designation.

There is also shown one of a number of bars |31 (Fig. 2) which extendthrough the wall 351 and into the transfer mechanism mentioned above,each of said bars being controlledV from an additional control pin inthe box |090.- that has an extension ||3 that trips the lever |45 when'said pin is elevated by the previously mentioned' additional' pin |04'in'the lower pin box |03a. Allof' the levers |45 are carried by a'common bail: 229 which is rockingly supported on the'shaft 230 extendingbetween the rails 39' and' said' shaft is controlled by'a cam on theshaft 58 which op'- erates a bellcrank 232. A link 223` detachablyconnects saidv bell crank` to an arm carried by the rock shaft 2'30so asto turn the latter clockwise to operate said bail and thereby cause 4anylever |45 tripped by a control pin ||3 to impart movement to its'associated bar' |31'. This' act'ion" ofthe bail'takesplace before'thescanning device 2|| starts its movement to the' right andthe` b'ail" isthereafter restored by the'spring 2'35 connected to the bell crank'232;

A panel 300 is' attached. to the wall' 35 and carries the' switchesandkeys employedV for acfcomplshing various controls of the machine.

With the'pa'rts in the position of Fig. l', should it be desired to opentheV analyzing unit', itis only necessary to remove the dowel screws 43and'un latch the keepers 30| to' disconnect the' upper ends. of theleversland' links |'2|', |26, 2|B, 2`|8u` and 223 from their respectivecrank arms and links on both sides of the machine, whereupon the entireauxiliary frame and parts supported* thereby may beswungupwardly aboutthe pivots 38 to open position.
